Development of a mathematical model for the numerical study of a thermal control system fluid circuit

This paper considers the development of a mathematical model for spacecraft thermal control fluid circuit systems. The need to take into account the complex mode of heat exchange in a fluid circuit model reflects relevance of the paper. Basic equations of heat exchange model in the circuit are given. A procedure for the numerical solution is described. Obtained calculation results are presented and analyzed. The developed model allows numerical studies to assess an impact on characteristics of the circuit of various design and operating parameters.
